PATENT HIRAM T. KING, OF ROCHESTER, NEW YORK.

FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 276,050, dated April17, 1883.

Application filed March 27, 1882. i

To all whom it may concern:

Be it known that I, HIRAM T. KING, of Rochester, Monroe county, NewYork, have invented a certain new and useful Improvement in Sash-Locks;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being bad to the accompanyingdrawings, in which- Figure l is a plan of the device attached to themeeting-rails of two sashes and locking them together. Fig. 2 is avertical cross-section in line was of Fig. 1. Fig. 3 is afront edge viewof the case, showing the locking socket or slot.

My improvement relates to looks for securing the meeting-rails ofsashes, and is of that class where one half of the lock-case is on onerail and the other half on the other rail, and a lever is used pivotedto one half, which lever swings over the other'halt', thus preventingthe upper sash from falling and the lower sash from rising.

My invention consists in the combination of the rear part of thelock-case provided with an eccentric pivot, reversible in position, aswinging lever, having a hook on its outer end, turned downward andbackward, and the front part of the lock-case, formed with a hole orslot, and with a guide-rib, all constructed, arranged, and operating ashereinafter specified.

In the drawings, A A show the meetingrails of two sashes, one being theupper and the other the lower sash.

B B are the two halves of the lock-case, one half being secured to onerail and the other to the other rail by screws, as shown. The case maybe circular, or of any other form desired, but is made hollow on theunder side. In the front edge of the outer half is made an open notch,a, which opens through the shell to the interior, and on one side of thenotch is a horizontal guiding-lip, c, which projects over, forming arib, and extends along some distance, finally vanishing in the circle ofthe case.

0 is the swinging lever, pivoted to the inner half of the case andswinging across the joint, and having at its outer end a book, 1), whichNo model.)

engages with the slot a. Thelower end of the hook is turned inward andbackward horizontally, and when the lever is turned forward this hookpasses under the lip c and is guided by it to the notch.

D is the eccentric and pivot upon which the lever turns, the leverhaving an eye or hearing, d, which fits upon the eccentric, as shown inFig. 2. The eccentric consists of the eccentric portion f, upon whichthe eye of the lever fits, a thumb-piece, g, or other device at the top,by which the eccentric is turned, and a pin, h, at the bottom, fittingin a socket of the case, and forming the center on which the pivotturns, said pin having a washer, '5, below, or being otherwise attachedto retain its place.

So far as the mere use of a divided case attached to the rails of theopposite sashes and a pivoted lever which swings across the joint andprevents the sashes from being moved is concerned, they are similar toother sash-locks now in use; but in addition to these features theeccentric to which the lever is pivoted gives an end or drawing movementto the lever when operated, and causes the hook I) to strike into theslot a, thereby locking the le ver in place and preventing it from beingeither pushed up or turned around. The eccentric acts the double purposeof an eccentric to operate the lever and a pivot toturn it around upon.A half-turn of the eccentric in either direction is sufficient to lockor unlock the lever, and when free it can be swung freely around thesame, as any lever in this class of locks. In this invention the leveris positively locked in place and is immovable till unlocked again;hence it cannot be moved by inserting a knife or other thin instrumentin the crack between the rails, as in many locks of this class. Thelever is held open by turning over an inclined lug and stop, 1", on thecase, or by any other suitable means.

I do not claim, broadly, in a sash-lock, a swinging lever, aneccentric,,or a hollow case; but
